The base and hypotenuse of a right-angled triangle are 9 cm and 41 cm respectively. What is the area of the triangle? |
180 cm2 170 cm2 190 cm2 160 cm2 |
180 cm2 |
We know that, Area of right angled triangle = \(\frac{1}{2}\) × Base × Height h2 = p2 + b2 Base = 9 cm, Hypotenuse = 41 cm So, p2 = 412 – 92 = p2 = 1600 = p = 40 So, the area of right angled triangle = \(\frac{1}{2}\) × p × b = area of triangle = \(\frac{1}{2}\) × 40 × 9 = 180 cm2 |
