Please solve this question fastly please please please please please please​

Answer 1

Answer:

Area covered by the three roads 344 square meter

Step-by-step explanation:

Area of  the rectangular field 80 x 48 = 3840 sq meter

Area of the  road parallel to the breadth  = 2 x 48 = 96 sq meter

so two roads are parallel to breadth side =2 x 96 =192 sq meter

Area of the  road parallel to the length  = 2 x 80 = 160 sq meter

Now this  road parallel to the length crosses the 2 road parallel to the breadth side. area of the crossing region is 2 x 2 = 4 sq meter.

Crossing happens twice, area of crossing is 2 x 4 =8 square meter

Area covered by the three roads is = two roads are parallel to breadth side+Area of the  road parallel to the length -area of crossing

=192+160-8

=344 square meter
