Question

D
1. In a square ABCD, AB = (3x – 7) cm and BC = (x + 3) cm. Find the length
​

Answer 1

Answer:

Step-by-step explanation:

From the question,

• AB = BC = CD = DA             (∵ABCD is a square)

• 3x - 7 = x + 3

• 3x - x = 7 + 3

• 2x = 10

• x = 5

If you understand this then give me brainliest please.....

Thank you dear...

Always be happy....

Answer 2

Answer:

given ABCD is a square

AB= (3x - 7 ) cm

BC = ( x + 3) cm

Step-by-step explanation:

AB = BC ( sides of square are equal)

i.e 3x - 7 = x + 3

so, 3x - x = 3 + 7

2x = 10

x = 10 / 2

x = 5

so, AB = ( 3x - 7) = 3 * 5 - 7 = 15 - 7 = 8 cm

& AB = BC = 8cm
