Question

the areaof a right angle triangle is 143cm2.if one side containing the right angles is 13.8 cm find other side.​

Answer 1

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 = 17.5cm

so the other side is 17.5 centimeters
