Question

(2) The triangle has an area of 7 & 7/8 cm2 and a base of 5 & 1/4 cm. What is the

Answer 1

Answer:

h = 3 cm

Step-by-step explanation:

The area (A) of a triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the height )

Here A = 7 $\frac{7}{8}$ = $\frac{63}{8}$ ← expressed as an improper fraction

and b = 5 $\frac{1}{4}$ = $\frac{21}{4}$, thus

$\frac{1}{2}$ × $\frac{21}{4}$ × h = $\frac{63}{8}$, that is

$\frac{21}{8}$ h = $\frac{63}{8}$

Multiply both sides by 8 to clear the fractions

21h = 63 ( divide both sides by 21 )

h = 3
