Question

chess board is made up of 16 64 squares 32 black and 32 white the area of each square each square in the chess board is 6.25 CM square the border around the board is 1 cm wide find the area and perimeter of the chess board ​

Answer 1

Answer:

perimeter =88cm

area=484 cm^2.please give me a rank.

Step-by-step explanation:

because area of each square is 6.25 cm^2

so

side of each square is 2.5cm(square root of 6.25)

so

length of board = 2.5×8+1+1=22cm

(1,1 for border and 2.5×8 is for 8 squares in length side)

now

As each side of square is same.

so perimeter =4×22=88

area= side×side=22×22=484 cm^2

Answer 2

Step-by-step explanation:

Length of square Board is 32x6.5+2=227cm

area=227^2 = 51529cm2 = 5.1529m2

Perimeter=4x227 = 908cm = 9.08m
