Question

if the length is reduced by 1 cm and the breadth is increased by 2 cm a rectangle becomes a square if the perimeter of a rectangle is 34 cm find the area of the recta​

Answer 1

Answer:

geometry, an equilateral triangle is atriangle in which all three sides are equal. In the familiar Euclidean geometry, anequilateral triangle is also equiangular; that is, all three internal angles are also congruent to each other and are each 60°.

Answer 2

Answer:

60cm²

Step-by-step explanation:

Let the length of the rectangle be 'x' cm

and breadth be 'y' cm respectively.

A/Q,

=> x(length) = (2y + 2) cm ---> (1)

Now,

Perimeter of the rectangle = 2(l + b)

=> 34 = 2(x+y)

Putting the value of'x'

=> 34 = 2(2y + 2 + y)

=> 34 = 2(3y + 2)

=> 34 = 6y + 4

=> 30 = 6y

=> y = 5 cm

Now, putting the value of 'y' in equation (1) we get

=> x = 2y + 2

=> x = 2(5) + 2

=> x = 12 cm

Hence,

Length = 12 cm

Breadth = 5cm

∴Length of the triangle = 12×5 = 60cm²
