Question

Find the base of triangle, where height = 31.4 mm and area = 1256 mm

Answer 1

Answer:

Step-by-step explanation:

Area of a tri=1/2×b×h

1256=1/2×b×31.4

1256×2/31 .4=b

12560×2/314=b

40×2=b

B=80mm

Hope its helps u..

Answer 2

Answer:

WE KNOW THAT :-

AREA OF TRIANGLE = 1/2 × BASE × HEIGHT

==> 1256 MM = 1/2×31.4 × BASE

==> 1256 = 15.7 × BASE

==> 1256/15.7 = BASE

==> BASE = 80 MM
