Question

5. The area of a rectangle with breadth 8 m is 15 m² more than that of a
square with side 9 m. What is the length of the rectangle?
(1) 9 m (2) 12 m (3) 15 m (4) 20 m​

Answer 1

Answer:

Area of square = 9×9 = 81 m²

Area of rectangle = 81+15 = 96 m²

if breadth is 8 m, then length of rectangle = 96/8 = 12 m

Answer 2

Answer:

2. 12m

Step-by-step explanation:

area of square : 81

area of rectangle: 81+16=96

area of rectangle: l×b

96=8×x

x=96/8

x=12
