A triangle is within a rectangle. how to find the ratio of the area of triangle to the rectangle?
Sounds like the triangle is spread out so that (the point is at the top of the rectangle) and (the base of the triangle is the same as the base of the rectangle).Base of rectangle = base of triangleHeight of rectangle = height of triangleWrite the formulas:Area of the rectangle = (base) times (height)Area of triangle = (one half of) (base) times (height)Can you see the ratio now ?
How is the triangle formula derived from the area of rectangles?
The area of a triangle is expressed using the formula A=(1/2)(bh) Where A is area Where B is length of the base of the triangle. Where H is the height of the triangle. The area of a rectangle is A=BH, Where B is the length of the base of the rectangle. Where H is the height of the rectangle. Because a triangle, essentially, is a half of a rectangle, you find the area of the whole rectangle that the triangle comes from, then divide that in half.
How do you find the area of a rectangle and any triangle?
Rectangle: length x width triangle: (base x height)/2
How do you find the area of the shaded part of a rectangle that is 12 inches by 9 inches that has a lopsided triangle non shaded in the center?
You either need to find the area of the triangle and subtract it from that of the rectangle OR you find the areas of the bits of the rectangle that are outside the triangle and add them together. Without more details of the triangle, it is not possible to give a more detailed answer.
How could you use the formula for area of a rectangle to find the formula for the area of a triangle?
A traingle covers half the area of a rectangle with the same base and [perpendicular] height.

How do you find the area of a rectangle with a triangle attached to the side?
you split your shape in half, (The rectangle and the triangle), by putting a line through it and then calculate the area of the rectangle and then calculate the area of the triangle, half the area of the triangle then add the area of the triangle and the rectangle together!Then you should have your answer!

Find the area of 6 base and 10 height?
If the figure is a rectangle, the area is 60. If the figure is a triangle, the area is 30.
How do you find the height when you know the Area and the base?
in a triangle double area and divide by base in a rectangle divide area by base
How do you calculate the area of one arrow sign?
To find the area of an arrow you can first divide it into two shapes, a rectangle and triangle. First find the area of the rectangle then the area of the triangle. Then when you find both areas of the two shapes add them up to get the area of the arrow. If you don't know how to find the area of those two shapes you are so far lost.
How do you find the area of a hexagon given the area of the rectangle formed by 2 diagonals and 2 sides of the hexagon?
L x B which gives the area of th rectangle then remaining we will have 4 equator triangle 1/3BH3 is the are for the triangle. cumulatively we will get area for the hexagan.
What is the rectangle method in math?
The term "rectangle method" is used in different ways in math, but I will guess that your question is related to finding areas on a Geoboard. A Geoboard has a grid of pegs; you can make outlines of figures by stretching elastic bands around the pegs. If your figure is a triangle, you can find it's area by making the smallest rectangle which will enclose the triangle (The rectangle should have vertical and horizontal sides). The area of the rectangle can be found easily by multiplying the length by the width. The area of the triangle is half of the area of the rectangle.
How do you find the area of a 45-45-90 triangle?
The base times the height divided by two. Imagine a right triangle is half of a rectangle. The area will also be half.
