Answer:

x(smaller)=4, y(bigger)=5

Step-by-step explanation:

(2x+3)*y=55

11*5=55

so, 2x+3=11

2x=8 after subtracting 3 from both sides

x=4 after dividing by 2 from both sides

y is then equal to 5 because 11y=55

divide both sides by 11, you get y=5, which means y>x, and y is the larger number.

Answer:

length = 20cm

breadth = 8cm

Step-by-step explanation:

solution;

length(l) = x + 12

breadth(b) = x

perimeter (p) = 56 cm

we know that,

perimeter(p) = 2(l + b)

or, 56 = 2(x + 12 + x)

or, 56 = 2(2x + 12)

or, 56 = 4x +24

or, 56 - 24 = 4x

or, 32 = 4x

or, 32 / 4 = x

x = 8

now

putting the value of x in length and breadth

length = x+ 12

=8 + 12

=20cm

breadth = 8cm
