Question

The sides of a right angled triangle are of lengths 0.12 m, 15 cm and 0.09 m. Find its perimeter and
area.​

Answer 1

Answer:

perimeter is 15.21

Step-by-step explanation:

area is 0.675

Answer 2

Answer:

Area = 0.009 m²

Perimeter = 0.36 m

Step-by-step explanation:

Area of right angled triangle

= 1/2 × base × height

= 1/2 × 0.12 m × 0.15 m

= 0.009 m²

Perimeter of right angled triangle

= Sum of all sides

= 0.12 m + 0.15 m + 0.09 m

= 0.36 m

NOTE : 15 cm = 0.15 m
