Question

A rectangle is formed by placing two identical squares side by side .The area is 242 cm 2 what is the perimeter of the rectangle

Answer 1

Answer:

The answer is 200 dm^2

Step-by-step explanation:

A rectangle is formed by placing two identical squares side by side. The perimeter of the rectangle is 60 dm.

In order to find the area of a rectangle we must use the formula A = L x W

S = Side of a square

3s+3s=60

6s=60

s=10

Area of Rectangle

L=10 dm+10 dm=20dm W=10dm

A = 20dm x 10 dm = 200dm^2

Answer 2

Answer:

L = 11

b = 22 cm

h = 11 cm

P = 66 cm

Step-by-step explanation:

rectangle

A = b * h

square

A = L²

Two squares

A + A = L² + L²

2A = 2L²

242 = 2L²

L² = 242 / 2

L² = 121

L = 11

b = 2L

b = 2(11)

b = 22 cm

h = 11 cm

P = 2b + 2h

P = 2(22) + 2(11)

P = 66 cm
