Question

Which of the following shows the possible dimensions of a triangle of area $100m^2?$

• A. Base (b) = 20 m, Height (h) =10 m
• B. Base (b) = 25 m, Height (h) =10 m
• C. Base (b) = 25 m, Height (h) =8 m
• D. Base (b) = 50 m, Height (h) =10 m

Answer 1

Answer: (A), (C)

The correct options are
A Base (b) = 20 m, Height (h) =10 m
C Base (b) = 25 m, Height (h) =8 m

$\text{Area of triangle}=\frac{1}{2}\text{base}\times \text{height}$

when,
Base (b) = 20 m, Height (h) =10 m
$\text{Area of triangle}=\frac{1}{2}\times 20\times 10$
$=100m^2$
when,
Base (b) = 25 m, Height (h) =8 m
$\text{Area of triangle}=\frac{1}{2}\times 25\times 8$
$=100m^2$
