Question

Find the cost of leveling a plot of ground in the form of a quadrilateral at Rs. 2.50 per sq. meter whose diagonal measures 75 m and its offsets measure 50 m and 40 m respectively.

• A. Rs. 4837.50
• B. Rs. 8437.50
• C. Rs. 8456.90
• D. Rs. 7426.20

Answer 1

The correct option is B

Rs. 8437.50

Here diagonal AC = 75 m

BL = 40 m and DM = 50 m

Area of quad. ABCD

$=\frac{1}{2}\times AC\times (BL+DM)$

$=\frac{1}{2}\times 75m\times (50m+40m)$

$=75\times 45m^2$

$=3375m^2$

The cost of leveling a plot = 3375 $m^2$ × 2.50 Rs./$m^2$

= Rs. 8437.50
