The area of a triangle is 785.9cm², the height is 15.6cm. find the base

b=100.7564103 approx

Step-by-step explanation:

formula is

A=0.5*b*h

785.9=0.5*b*15.6

         =b*7.8

785.9 / 7.8= b

base ≈ 100.76 cm ( to 2 dec. places )

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = bh ( b is the base and h the height )

Here A = 785.9 and h = 15.6, thus

× b × 15.6 = 785.9, that is

7.8b = 785.9 ( divide both sides by 7.8 )

b ≈ 100.76

answer: i believe its b. if you sound out the sentences that sounds wrong.
