ANSWER:-
(19)...
one side= 3x+5
second side= 2x-3
let the third side be y
so, 3x + 5 + 2x - 3 + y = 8x - 7
5x + 2 + y = 8x - 7
(since like terms can be added and Sunbtracted)
y = 8x - 7 - 5x - 2
y = 3x - 9
so, option (d) 3x - 9 is the right answer.
(20)...
let the breadth will be x
then length will be x+2
a/q
2 (x+2+x)=36
2 (2x+2)=36
2x+2=18 (divide2 in36)
2x=18-2
x=16/2
x=8
breadth =x=8
length =x+2=8+2=10m
