Answer:
375
Step-by-step explanation:
perimeter =70
length=25
breadth=b
perimeter =2(l+b)
70=2(25+b)
70=50+2b
2b=70-50
2b=30
b=15
area of rectangle = l×b
25×15
=375
area of rectangle=375

Perimeter = (L×2)+(b×2) = 70 cm
length = 25 cm
breadth = 70-(25+25) = 70-50 = 20
= 20÷2 = 10 cm
area = L×b = 25×10
= 250 cm²
