Question:

The diagonal of rectangle is 15 cm and length is 12 cm. Find the area of the rectangle.

Options:

108 cm2

116 cm2

114 cm2

112 cm2

Correct Answer:

108 cm2

Explanation:

We know that,

H2 = P2 + B2

Area of the rectangle = Length × Breadth 

Given,

Diagonal of rectangle = 15 cm

Length of the rectangle = 12 cm

 According to the formula,

152 = 122 + B2

= B2 = 225 – 144 

= Breadth = 9

Area of the rectangle = 9 × 12 = 108 cm2
