Question

8. Find the area of a triangle with base 5 cm
and whose height is equal to that of a
rectangle with base 5 cm and area 20 cm​

Answer 1

Base = 5 cm

Area of ∆= 20cm

1. 20cm = L×B
2. 20cm = 5×B
3. 20cm = B

5

4. 4cm = B

hence height of ∆= 4cm

1. Area of ∆= 1/2 ×B×H
2. = 1/2× 4cm ×5cm
3. = 10 sq.cm.
