Answer:
324
Step-by-step explanation:
L = 4W
P = 2L + 2W = 90
---
2L + 2W = 90
2(4W) + 2W = 90
8W + 2W = 90
10W = 90

Answer:
The area of the rectangle is 324 square centimeter.
Step-by-step explanation:
What is area?
The area is the amount of space within the perimeter of a 2D shape.
What is rectangle?
A rectangle is a two-dimensional shape (2D shape) in which the opposite sides are parallel and equal to each other and all four angles are right angles.
What is perimeter?
Perimeter is the distance around the edge of a shape.
Let the width of the rectangle be x cm.
Then, the length of the rectangle = 4xcm
Perimeter = 2(length + breadth )
90 = 2(4x+x)
90 = 2*5x
90 = 10x
x = 90/10= 9cm
Width = 9cm
Length = 4*9 = 36 cm
Area = Length*Breadth
=9*36
=324 square centimeter.
