Okay:
For line “l”: y=4
For line “m”: y=-2/1+4
For line “p”: x=-4
For line “n”: y=1x-1
Answer:
A
Step-by-step explanation:
Answer:
let 3:2 be 3x& 2x
perimeter =40
2(l+b)=40
2(3x+2x)=40
5x=40/2
x=20/5=4cm
length=3x=3×x=3×4=12cm
breadth =2x=2×4=8cm
area of rectangle =l×b=12×8=96cm²
3x+x=96
(4x=96)/4
x=24
3(24)=72
Hector is 24 and his grandma is 72.
hope this helps!
