Question

the area of a right angle triangle is 40 square CM if its base is equal to 28 cm find its height​

Answer 1

Answer:

The area of a right angled triangle is 40 sq cm. If its base is equal to 28 cm. find its height

A) 367cm

B) 467cm

C) 267cm

D) 567cm

 

Correct Answer:

C) 267cm

Description for Correct answer:

Given that, area = 40 sq cm. base = 28 cm and height = perpendicular = ?  

Area = 12×Base×Perpendicular  

=> 40 = 12×28×Perpendicular

Perpendicular =4014=207

=267cm

Answer 2

$area \: of \: triangle \: = \frac{1}{2} \times base \times height \\ 40 = \frac{1}{2} \times 28 \times h \\ h = \frac{40 \times 2}{28} \\ h = \frac{80}{28} \\ = 2.85cm(approx)$
