Question

a triangle has an area of 11.6sqcm if it's height is 2.9cm what is it's base​

Answer 1

Answer:

8cm

Step-by-step explanation:

base = x

height = 2.9cm

Area = 11.6 cm²

we know that area of triangle = 1/2×b×h

= 1/2×x×2.9 = 11.6

x = 11.6×2/2.9 = 8cm

Answer 2

Answer:

Area = ½×base×height

Or 11.6cm² = ½×base×2.9

Or base = 11.6×2/2.9 = 4×2 = 8cm Ans
