Question

perimeter of a rectangle is 144 CM if one of the two adjacent sides to 20cm longer than the other then the area of triangle is​

Answer 1

Hey mate ,

Let the breadth of the rectangle be x cm

Thus , Length of the rectangle = (20+x) cm

Area of rectangle = 2(l+b)

144 = 2(20+x+x)

72 = 20+2x

52 = 2x

x = 26 cm

Thus breadth = 26cm

length = 46 cm

Idk what kind of triangle you are asking about!!

Hope you find it helpful!!!!

Do mark it as brainliest!!!

Answer 2

Step-by-step explanation:

2(l+b)=144cm

(l+b)=72cm (1)

l=b+20. (given)

2b+20=72. (given value to put in eq .1)

2b=52

b=26cm

l=46cm

Area of rectangle =l×b

=26×46=1196cm^2
