Question

The area of rectangle and parallelogram are equal if the length and breadth are 8 cm and 4.5 cm respectively and the base of the parallelogram is 9 cm then find the altitude to the base of the parallelogram

Answer 1

Answer:

4 cm

Step-by-step explanation:

Given that Area of rectangle and Area of parallelogram are equal

So first find area of rectangle that l =8cm and b =4.5cm

Area of rectangle = l * b

= 8 * 4.5

= 36 cm sq.

So, Area of parallelogram = 36 cm sq (given)

Now, Area of parallelogram = base * height

Height = area of parallelogram ÷ base

Height =36 ÷ 9

Height = 4 cm

Answer 2

Step-by-step explanation:

Area of rectangle is equal to area of parallelogram

Area of rectangle= length × Breadth

= 8 × 4.5

= 36 cm sq .

Area of parallelogram= 36 cm sq

Area of parallelogram= base × height

36 =9×height

height = 36÷9

= 4 cm
