Question

area of rectangle is 192cm & its breadth is 12cm. find the perimeter and the diagonal of the rectangle​

Answer 1

Given :-

Area of rectangle is 192cm & its breadth is 12cm.

To Find :-

Perimeter

Diagonal

Solution :-

We know that

Length = Area/Breadth

Length = 192/12

Length = 16 cm

Perimeter = 2(l + b)

Perimeter = 2(16 + 12)

Perimeter = 2(28)

Perimeter = 56 cm

Now

Diagonal² = Length² + Breadth²

D² = (16)² + (12)²

D² = 256 + 144

D² = 400

D = √(400)

D = 20 cm
