Question

A rectangular garden with dimension 77mx44m is to be constructed, 2 roads each 3.5m wide runs across the middle of the garden, one parallel to the length and the other parallel to the breadth. Find the total area of roads.​

Answer 1

Answer:

Total area of the 2 roads

= 77 × 3.5 + 44 × 3.5

= 269.5 + 154 = 423.6m^2

Answer 2

Answer:

PLS MARK AS THE BRAINLIEST

$411.25m^{2}$

Step-by-step explanation:

Dimension of garden = 77m × 44m

Width of road = 3.5m

Dimension of 4 small rectangles = (77m-3.5m)/2 × (44m -3.5m)/2

Area of 4 small rectangles =  $744.1875m^{2}$ × 4 = $2976.75m^{2}$

Area of garden = 77m × 44m = $3388m^{2}$

Area of road = $3388m^{2}$-$2976.75m^{2}$ = $411.25m^{2}$
