Answer 2

Answer:

diagonal of rectangle is 10cm

Step-by-step explanation:

given fig is rectangle

hence, we use the formula for finding diagonal is -

(diagonals)^2 = (length)^2 + (width)^2

length = 8cm , width = 6cm , diagonal = x

x^2 = 8^2 +6^2 = 64 + 36

     = 100

x = (100)^(1/2) = 10

diagonal = 10cm
