## anonymous 5 years ago TWO TIMES THE BASE OF A PARALLELOGRAM IS EQUAL TO 3 TIMES THE SIDE. THE PARALLELOGRAM HAS A PERIMETER OF 800. WHAT IS ITS BASE? AND SIDE?

If b is the base and s the side, you're told,$2b=3s$You also know that $2b+2s=800$You have two linearly independent equations in two unknowns - you can solve this system. Since the first equation gives 2b=3s, you can write for the second equation,$2b+2s=3s+2s=800 \rightarrow 5s=800$Therefore$s=160$Substitute this into the any one of the two original equations to get for the base,$2b=3 \times 160 \rightarrow b=240$

Is it just the four questions in capitals?
