a b) You are running around a rectangular ground of length 42 m and breadth 24 m. How many metres do you cover when you complete

prisoha [69]

Answer:

792 m

Step-by-step explanation:

perimeter of a rectangle = 2l + 2b

⇒ perimeter of ground = (2 x 42) + (2 x 24) = 132 m

Perimeter = 1 round

⇒ 6 rounds = 6 x 132 = 792 m

Answer:

Step-by-step explanation:

This is the method I am familiar with.

I Hope It helps :)

$METHOD- 1 : Elimination\\6x - 2y=10------(1)\\2x+3y =51------(2)\\Multiply -eq-(1)- by -the-coefficient-of-x-in-equation (2)\\Multiply-eq-(2) -by -the-coefficient-of-x-in-equation (1)\\6x - 2y=10------(1) *2\\2x+3y =51------(2)*6\\\\12x-4y=20 ------(3)\\12x+18y=306 ------(4)\\Subtract -eq- (4)- from- eq -(3)\\-22y =-286\\\frac{-22y}{-22} =\frac{-286}{-22} \\y =13\\$

$Substitute- 13- for y -in-equation -(1)-or-(2)\\6x - 2y=10------(1)\\6x -2(13)=10\\6x -26=10\\6x =10+26\\6x =36\\\frac{6x}{6} =\frac{36}{6} \\x =6$
