Question

This square is formed using four identical rectangles. If the perimeter of the square is 80 cm, find the perimeter of each rectangle.

Answer 1

Answer:

Step-by-step explanation:

Using 4a=perimeter

Side=20cm

As there are four rectangle of same width and same length so half the side of square is 10 cm which is side of rectangle

Perimeter=40cm using formula

2(l+b)

B=10cm

L=10cm

Answer 2

Answer:

PERIMETER OF SQUARE = 80 cm or m

Side = ?

Therefore side will be x

Perimeter of square = 4× Side

80= 4×X

80=4X

80÷4=X

X = 20

Therefore the side will be 20
