Question

Find the answer of height of triangle having base =8.5m , area =28.9m^2.

Answer 1

As we know that the formula for finding the area of a triangle is 1/2×b×h.

Here in the question

b =8.5m=85/10m

area=28.9m square =289/10m square

=> 1/2 ×b×h= area

=> 1/2 ×85/10×h=289/10

= 85h/20=289/10

=85h×10=289×2

=850h=5780

=h=5780÷850

=h=68/10=6.8.

Hence , the height is 6.8 m.

Answer 2

area of rectangle triengle =1/2 ×base× hight

28.9=1/2×8.5×hight

289/10=1/2×85/10×hight

hight=289×2/85

hight =6.78

I hope this answer is righr
