1.	The area of the right triangular region is 129.5 cm2. If one of the sides containing the right angle is 14.8 cm, find the other one.
Answer» Let the length of the other side be h cm. Then, area of the triangle = (1/2) × base × height 129.5 = (1/2) × 14.8 × h 129.5 = 1 × 7.4 × h 129.5 = 7.4h h = 129.5/7.4 h = 17.5 cm Hence, the length of the other side is 17.5 cm

The area of the right triangular region is 129.5 cm2. If one of the sides containing the right angle is 14.8 cm, find the other one.

Answer»

Let the length of the other side be h cm.

Then, area of the triangle = (1/2) × base × height

129.5 = (1/2) × 14.8 × h

129.5 = 1 × 7.4 × h

129.5 = 7.4h

h = 129.5/7.4

h = 17.5 cm

Hence, the length of the other side is 17.5 cm
