Question

the area of triangle is equal to area of a rectangle whose length is 45 cm and breadth is 24 cm. find altitude of triangle if base of triangle is 80 cm

Answer 1

Answer:

Height = 12 cm

Step-by-step explanation:

Area of Rectangle = Length × Breadth

Length = 45 cm

Breadth = 24 cm

Area = ( 45 × 24 ) cm

Area = 1080 cm²

It means that the area of triangle is also 1080 cm²

Height (Altitude) = $\frac{1}{2} * base / area$

Base = 80 cm

Area = 1080 cm²

Height = $\frac{1}{2}$ × 80 cm

= $\frac{1080}{40}$

Height = 12 cm
