Question

in rectangle adjacent side measure x+2 and 2x-3 and perimeter =40

Answer 1

Answer:7cm

Step-by-step explanation:

Perimeter = 2( length + breadth)

40 = 2( x+2 +2x-3)

20=3x-1

3x=21

x=7

@skb

Answer 2

$2[(x + 2) + (2x - 3)] = 40 \\ 2[x + 2 + 2x - 3] = 40 \\ 2[3x - 1] = 40 \\ 6x - 2 = 40 \\ 6x = 42 \\ x = \frac{42}{6} = 7$
Hence, Sides of rectangle is 9 cm and 11 cm
