Question

A traingle and a parallelogram have theh same base and the same area if the sides of the traingle are 26 cm , 28 cm and 30 cm and the parallelogram stands on the bse 28 cm , find the height of the parallelogram​

Answer 1

Answer:

h = 12 cm

Step-by-step explanation:

Perimeter of Triangle

2S=26+28+30=84

⇒S=42cm

Area s(s−a)(s−b)(s−c) (Heron's formula)

Area =42(42−26)(42−28)(42−30)=42×16×14×12

Area=336cm2

Area of parallelogram = Area of triangle

⇒ h×28=336

⇒h=12cm
