b) Its perimeter
​

Answer 1

Answer:

Hey friend,

Here is the answer you are searching for,

Given,

Area = 260 cm²

Length = 20 cm

Let the breadth be x,

A.T.Q,

Area = Length × Breadth

= 20 × x = 260

=> x = 260/20 = 13 cm

=>Breadth = 13 cm

=> Perimeter = 2(Length+Breadth)

= 2(20+13)

= 2×33

= 66 cm.

Hence,

a) Breadth = 13 cm.

b) Perimeter = 66 cm.
