Question

What is the value of x and y.
1) x=40,y=36
2) x=8,y=6
3) x=6,y=16
4) x=16,y=6

Answer 1

Answer:

(3)

Step-by-step explanation:

side length of rectangule is given . So, equating the width with width and length with length.

3(y-4) = 36. 5(x+2) = 40 .

y-4 = 36 ÷ 3 = 12. x+ 2 = 40÷5 =8.

y = 12+4 = 16. x = 8-2 = 6.
