Question

(b) area = 8 sqmm and length = 5 mm. find the primeter​

Answer 1

Answer:

The perimeter of the rectangle is 17.2mm

Step-by-step explanation:

Question says that, Area of a rectangle is 8mm² and it's length is 5mm.So, find the perimeter of the rectangle.

Step 1 : Finding the width of the rectangle :

Area of the rectangle = length × breadth

Or,

→ 8 = 5 × breadth

→ 8/5 = breadth

→ 1.6 = breadth

∴ The width of the rectangle is 1.6mm

Step 2 : Finding the perimeter :

Perimeter of a rectangle is given by :

→ 2(l + b)

→ 2(5 + 1.6)

→ 2(8.6)

→ 17.2mm

∴ The perimeter of the rectangle is 17.2mm

Answer 2

Perimeter of rectangle =19.2mm
