Question

which figure has a greater area? 78 yd 39 yd 61 yd 52 yd

Explanation:

Step1: Calculate area of green - triangle

Use formula $A=\frac{1}{2}bh$, where $b = 39$ yd and $h = 78$ yd. So $A_1=\frac{1}{2}\times39\times78=39\times39 = 1521$ square - yards.

Step2: Calculate area of blue - triangle

Use formula $A=\frac{1}{2}bh$, where $b = 52$ yd and $h = 61$ yd. So $A_2=\frac{1}{2}\times52\times61 = 26\times61=1586$ square - yards.

Step3: Compare areas

Since $1521<1586$, the blue - triangle has a greater area.

Answer:

The blue - colored triangle has a greater area.
