Suki wants to build a 60 ft. long rectangular sheep pen in back of her barn. if she bought 150 feet of fencing and used her barn wall as one side of the pen equaling the width, what would be the area of the sheep pen?

Length of the sheep pen =60ft

150 ft of fencing bought

One side of rectangular sheep pen is covered with barn which is equaling the  width

perimeter of rectangular sheep pen = 2(length +width)

length need to covered is 2 Length+ width

150 =2 length+width

150 = 2 x60 +width

150-120= width

30= width

Area of rectangle = 60 x 30

180 ft2

the wrong statement is - c. a desert had more biodiversity than a marsh.

the deserts are one of the places of the planet where there's the least biodiversity. the reasons for that are the climate and the lack of food sources, which hampers both the number of the species that can survive in it, and the number of the individuals in the species itself.

the marshes, on the other hand, are places where there's perfect conditions for lots of organisms to thrive. the temperature is moderate and nice, the amount of water and the food sources are on a high level, so there's an abundance of both plant and animal life in them.
