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!
How do you prove the formula for the area of a rectangle?
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
The legs of a right triangle are 12 and 16 inches long respectively What is the area of the triangle?
Lets work it out:- If the legs are 12 and 16 inches, then a rectangle of that size would be 192 square inches in area. As the the diagonal of the rectangle makes two equal triangles (of legs 12 and 16 inches), the area of one of these is half the area of the triangle - 192/2 = 96 square inches.
How do you find the area of a compound figure with there is a trapezoid and a rectangle?
Work out each figure separately then add them together: Area of a trapezoid = 0.5*(sum of parallel bases)*height Area of a rectangle = length*height
How many lines of symmetry do squares have?
The square has four lines of symmetry. The rectangle has only two, as it can be folded in half horizontally or vertically: students should be encouraged to try to fold the rectangle in half diagonally to see why this does not work.
How is the area of a triangle related to the area of a rectangle?
It's half the area of a rectangle
Why is the area of the triangle half the base times the height?
Because a triangle is half of a rectangle. The area of a rectangle is length times width, the area of a triangle is half that.

What happens to the area of a rectangle if you half the width?
It becomes half of what the original area is.
For each triangle draw the other half of a rectangle. What does this mean?
The area of qa triangle is always half of the area of a rectangle with the same dimensions
Can you explain why the area of a triangle is 1 half base height while the area rectangle or a parallelogram is expressed as base height?
If you draw a diagonal in a rectangle you get two equal triangles, each half the area of the rectangle. Area of rectangle is base x height, so half of that is ½ x base x height. QED
Is every triangle half of a rectangle?
No. Although the area of every triangle is equal to half the area with the same base and height, only right angled triangles are half a rectangle.
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 prove the formula for the area of a rectangle?
The formula for the area of a rectangle is length x breadth. In order to prove this works, work out an area of a rectangle using that formula.
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 is finding the area of a triangle different from finding the area of a rectangle?
the area of a triangle is base times height times one half and rectangle is length times width
How do you cut a rectangle in half?
With a knife scissors or anything else in that area!
