Question

2) a
Find the height of a triangle whose
a Area
= 80cm2 and base =8m

​

Answer 1

Answer:

20 cm

Step-by-step explanation:

A=

$a = \frac{1}{2} \times b \times h \\ 80 = \frac{1}{2} \times 8 \times h \\ \frac{80}{4} = h$

Therefore, H=20cm

Answer 2

Answer:

hb=2×10-3m

b Base

8

m

A Area

80

cm²

Unit Conversion:

b=8m

A=8×10-3m²

Using the formula

A=hbb

2

Solving forhb

hb=2A

b=2·8×10-³

8=2×10-³m
