Answer 2

Dear Student,

◆ Answer -

(A) 180 cm

(B) 610 cm

● Explaination -

(A) 40 cm, 20 cm, 30 cm, 50 cm, 40 cm -

Five sides are given here, so this is a pentagon.

Perimeter of the pentagon is calculated by adding lengths of all sides.

Perimeter = 40 + 20 + 30 + 50 + 40

Perimeter = 180 cm

(B) 100 m, 150 m, 270 m, 90 m -

Four sides are given here, so this is a quadrilateral.

Perimeter of the quadrilateral is calculated by adding lengths of all sides.

Perimeter = 100 + 150 + 270 + 90

Perimeter = 610 cm

Thanks dear.
