Since 12 isn't over 50, you would round to the lower hundred. The answer is 13,900.
2/-3 by using the formula y2-y1/x2-x1
take the breadth as x and accordingly length as (x+18)
the formula for finding the perimeter of a rectangle is 2(l+b) now put the correct values as shown in the picture and form an equation this way you will be able to find x which is the breadth and length Is 18 morethan breadth ,now as u have found both length and breadth go ahead and find the area whose formula is length×breadth
HOPE IT HELPS
Angle P is 50 degrees
OP is 17cm
They are similar quadrilaterals so their corresponding parts are congruent.
