Question

the area of triangle 90cm square Base is 15cm square find its altitude

Answer 1

hiii!!!

here's ur answer...

given the base of the triangle is 15cm.

area of the triangle = 90cm²

therefore 1/2×b×h = 90cm²

=> 1/2×15×h = 90cm²

=> 7.5×h = 90cm²

=> h = 90/7.5

=> h = 12cm

verification:-

area of the triangle = 1/2×b×h

= 1/2×15×12

= 15×6

= 90cm²

hence verified

thus the altitude of the triangle is 12cm.

hope this helps..!

Answer 2

12 is the correct answer

Area of Triangle=½× base×altitude
90cm²= ½× 15×Altitude
90×2÷15=Altitude
180÷15=Altitude
12 =Altitude

I hope it will help u
