Question

a lawn is 80metre long and 30 metre wide through the centre of the lawn two parts each 2 metre wide in the intersect each other at right angles find the area of the remaining portion of the lawn ​

Answer 1

Answer:

Outer Area =l*b

=80*30=2400m2

Inner length =(80-2-2)=(80-4)=76m

Inner Breadth =(30-2-2)=(30-4)=26m

Inner Area =l*b=76*26=1976m2

Area of remaining portion =2400-1976

Area of remaining portion =424m2
