Question

Two adjacent sides of the parallelogram are CD = 8 cm and AD = 6 cm. The height corresponding to the
base CD is 4 cm. Find the height corresponding to the base AD.
The perimeter of a rectangular sheet is 100 cm and its length is 35 cm, find its area.​

Answer 1

Area of the parallelogram = 1/2 × base × height

then,

1/2 × AD × 4 cm = 1/2 × CD × height

1/2 × 6 × 4 cm = 1/2 × 8 × height

height = 3cm
