Krista is building a pen for her bunny. She's planning to make it 5 ft long and 4 1/2 ft wide. She would like to build one with an area 3 times as big as that. But she doesn't have the room. How long would the pen be if she could make one that size?

Th perimeter of a rectangular garden is 150 feet. the length is 50 feet longer than the width, w. which equation could be used to calculate the width of the garden? a.) 2w+ 2(w-50) =150 b.) 2w+50 + 2w =150 c.) 2(w+50) + w =150 d.) 2w+ 2(w + 50) = 150 need asap. will give brainliest !
