Rectangular garden

Rectangular garden has a length of 48.7 m, a width of 6.3 meters shorter than the length. How much mesh should be bought for its fencing if the gate is 2.9 m long and the gate 1.1 m? What is the area of the garden?

Correct answer:

x =  178.2 m
S =  2064.88 m²

Step-by-step explanation:

$$\begin{gathered} a=48.7\text{m} \\ b=a-6.3=48.7-6.3=\frac{212}{5}=42.4\text{m} \\ c=2.9+1.1=4\text{m} \\ x=2\cdot (a+b)-c=2\cdot (48.7+42.4)-4=178.2\text{m} \end{gathered}$$

$S=a\cdot b=48.7\cdot 42.4=2064.88{\text{m}}^2$
