sum of age of Vishal and Manoj is 48 years. if the age of Vishal is three times the age of Manoj, find there age.

Step-by-step explanation:

let the age of Manoj be x

vishal's age = 3 × Manoj's age = 3x

now, sum of their ages are 48 years

so,

so age of Manoj = x = 12 years

age of vishal = 3x = 12 × 3 = 36 years

i hope it helped

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2
