Answer:
156.06cm
Step-by-step explanation:
sa=LW6
The equation of the area of a triangle is Area=Length×Width. We know area=256.5 and length is 18. So now we know 256.5=18×width. We then divide 256.5÷18 to get the width. The width is 14.25. Perimeter=legth+length+width+width. If width is 18 and length is 14.25 then we add up all 4 sides. 18+18+14.25+14.25=64.5. 64.5 is the perimeter
Answer:
264 cm^2.
Step-by-step explanation:
The area = 1/2 * height * sum of the parallel sides
= 1/2 * 12 * (28 + 16)
= 6 * 44
= 264 cm^2.
It would have changed by 1/3 is ur answer
