Question

The perimeter of a rectangular sheet is 100 cm. If the length is 35 cm, find its breadth. Also find the area.

​

Answer 1

Answer:

L = 15cm, Area = 525 cm ^2

Step-by-step explanation:

L = to find

B = 35cm

P = 100 cm

A = to find

Perimeter = 2(L+B)

100 cm = 2(L+35)

100 cm = 2L + 70

Subtracting 70 from both sides

100-70 = 2L + 70-70

30 = 2L

L = 15cm

Area = L*B

Area = 15*35

Area = 525 cm ^2
