(iii) 15.5 cm

Answer 2

Answer:

area of a triangle = 1/2 × base × height

1) given area = 81cm^2

given base = 15 cm

now substitue in formula

81 = 1/2 × 15 × height

height = 162/ 15

height = 10.8 cm

2) given area = 1256cm^2

height = 31.4 cm

substitute in the formula

we get base = 80 cm

3) given area = 170.5 cm^2

base = 22 cm

substitute in the formula

we get height = 15.5 cm
