What is the area to 63?
To determine the area, we need more information such as the shape or dimensions of the object.
The area and perimeter of 3 and 7?
Area of a rectangle = l x bso, 7x3=21 area=21 perimeter of a rectangle = 2(l+b) 2(7+3) = 2x10 =20 this is your answer by kitty kat amrita
What l shape has an area of 8cm?
A rectangle that is 2cm by 4cm has an area of 8cm. It also has a perimeter of 12cm.
How do you figure out the area of a room?
room is in cuboid shape, so by calculating length(L),breadth(B),height(H) we can find area by formula AREA=L*B*H
How do you calculate area of L SHAPE?
An L is two rectangles. Just make sure you only count the place where they intersect once.
How do you do area in math?
In order to measure area of an object in math you will have the multiply the objects witdth X (times) length then you will have your area or the inside of the object. Depends on the shape! For a rectangle or square it is A=L*B Depends on the shape! For a rectangle or square it is A=L*B Depends on the shape! For a rectangle or square it is A=L*B

How do you get the area?
The area depends on the shape. For example, the area of a circle = Pi*r^2 where r is the radius. The area of a rectangle = l*w, where l is the length and w is the width.

How do you find area of a irregular shape?
If it is in the shape of an L or close this is how you do it. First split it in to 2 rectangles. Then find the area of that by doing Length x After. Arther that just add them together and you have found the area!
What is the area of a rectangle whose perimiter is 42 cm?
The area can't exactly be determined here since we don't have enough information about the sides of the rectangles! We only know that the perimeter of the rectangle is 42 cm. Then: P = 2(l + w) where l is the length and w is the width. 42 = 2(l + w) 21 = l + w Solve for either w or l to get... w = 21 - l So by the area of the rectangle, we obtain: A = lw A = l(21 - l) = 21l - l² So we can't really determine the area of the rectangle. It's just the general form of the rectangle with the perimeter 42 cm.
What shape has a perimeter of 20 units and an area of 21 units?
A 7 by 3 rectangle.
How do you calculate area of L SHAPE?
An L is two rectangles. Just make sure you only count the place where they intersect once.
How do you determine surface area of a room?
Assuming the room is cuboid in shape, let L = length, W = width and H = height. The surface area = 2*(L*W + W*H + H*L)
