The diagonal of rectangle is 15 cm and length is 12 cm. Find the area of the rectangle.
Answer & explanation
Correct answer: option 1
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
