Question

A triangular flaglets has an area of 840 cm2. what is its base if its height is 48 cm?

Answer 1

base = 35 cm

Explanation:

the area (A) of a triangle is calculated as

A =
`(1)/(2)` bh ( b is the base and h the height )

given A = 840 and h = 48 , then

`(1)/(2)` × b × 48 = 840

24b = 840 ( divide both sides by 24 )

b = 35

then base is 35 cm
