Question

find the perimeter of the rectangles whose lengths and breaths are 7cm,5cm and 5cm,4cm8​

Answer 1

Step-by-step explanation:

Perimeter 1 = 2(12)= 24cm

Perimeter 2 = 2(9)= 18cm

Answer 2

Step-by-step explanation:

There are two rectangles (we will name rectangle 1 and

rectangle 2)

Rectangle 1-

Length = 7cm

Breadth = 5cm

Therefore, Perimeter = 2(l+b)

= 2(7+5)

= 14+10

= 24 cm²

Rectangle 2 -

Length = 5cm

Breadth = 4cm

Perimeter = 2(l+b)

= 2(5+4)

= 10+8

= 18 cm²
