Question

Please help what is the perimeter of this figure

Answer 1

the picture in the attached figure

let

AB=x

we know that

perimeter of the figure=10*x

perimeter=42.5 cm

so

42.5=10*x

x=42.5/10

x=4.25 cm

area of the figure=area of rectangle +area of square

area of rectangle=4.25*(4.25*3)----> 54.1875 cm²

area of square=4.25²----> 18.0625 cm²

area of the figure=54.1875+18.0625-----> 72.25 cm²

the answer is

72.25 cm²
