![]() Therefore, the length of the rectangle is 61 cm and width is 18 cm. Given : T he length is 7 more than 3 times the width. Given : Perimeter of the rectangle is 158 cm. Let "x" and "y" be the length and width of the rectangle respectively. If the length is 7 more than 3 times the width, find the area of the rectangle. The perimeter of the rectangle is 158 cm. Given : One number is 7 less than two times of the other. If one number is 7 less than two times of the other, then find the two numbers. So, the amount invested in the deposit A is $1200 and B is $1300. Lenin gets 10% income on deposit A, 20% income on deposit B and the total income earned be $380.įrom (1), we can plug x = 2500 - y in (2). Let "x" and "y" be the amounts invested in A and B respectively. If the total income earned be $380, find the amount invested in A and B separately He gets 10% income on deposit A and 20% income on deposit B. Lenin invests some amount in deposit A and some amount in deposit B. So, the number of boys in the school is 480 and girls is 400. Given : There is 20% more boys than girls.
