Question

11. A trapezium with its parallel sides in the ratio 11:3 is cut off from a rectangle whose sides
measure 98 cm and 12 cm. Thearea of the trapezium is 3/7 of the area of the rectangle. Find

rectangle.
pls answer me
I will make it brainliest​

Answer 1

Answer:

Step-by-step explanation:

HELLO HOPE U LIKE MY ANSWER

LENGTH OF RECTANGLE IS GIVEN AS =98CM

BREADTH =12

AREA=L*B=98*12=1176

...

AREA OF REC = AR OF TRAPEZIUM [if sides are 11x and 3 x to be considered]

1176=1/2 {11x + 3x} * h

then on solving x=14

first side=11*14=154

second side=3*14=42

hope u get it thank you
