Question

Kaju barfi was cut exactly in the middle as shown such that both the parts of the barfi were exactly equal. The area of one part of the barfi is ___

• A. $12c{m}^2$
• B. $6c{m}^2$
• C. $9c{m}^2$
• D. $8c{m}^2$

Answer 1

The correct option is B

$6c{m}^2$

Since both the triangular parts are exactly equal, the area of one part is half of area of kajubarfi.

Area of one part $=\frac{1}{2}\times$ Area of kajubarfi

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

$=\frac{1}{2}\times 4\times 3$

$=6c{m}^2$
