Answer:
area of rectangle is 2375/9 m²
Step-by-step explanation:
length of rectangle = 2x - 5
width of rectangle = x - 10
perimeter of rectangle = 80
perimeter of rectangle = 2(l+b)
80 = 2([2x-5] + [x-10])
80 = 2(2x - 5 + x - 10)
80/2 = 3x - 15
40 = 3x - 15
40 + 15 = 3x
55 = 3x
55/3 = x
length = 2x - 5 = 2 × 55/3 - 5
= 110/3 - 5
= (110 - 15)/3
= 95/3m
width = x - 10 = 55/3 - 10
= (55 - 30)/3
= 25/3m
area of rectangle = l × b
= 95/3 × 25/3
= 2375/9 m²
