Question

A piece of wire is 36cm long. what will be the length of each side if the wire is used to form a rectangle having breath 10cm

Answer 1

Answer:

Ans. 8 cm

Step-by-step explanation:

Perimeter = Wire = 36 cm

Breadth = B = 10 cm

Lenght = L

We Know,

Perimeter = 2(L+B)

So,

36 = 2(L+10)

36/2 = L+10

18 =L+10

L = 18-10

L = 8 cm

Lenght = 8cm
