(1 point) Let f(x, y)=x2ex2 and let R be the triangle bounded by the lines x=2, x=y/3, and y=x in the xy-plane.(a) Express ∫RfdA as a double integral in two different ways by filling in the values for the integrals below. (For one of these it will be necessary to write the double integral as a sum of two integrals, as indicated; for the other, it can be written as a single integral.)∫RfdA=∫ba∫dcf(x, y)dy dxwhere a= , b= , c= , and d= .And ∫RfdA=∫ba∫dcf(x, y)d d +∫nm∫qpf(x, y)d dwhere a= , b= , c= , d= , m= , n= , p= , and q= .(b) Evaluate one of your integrals to find the value of ∫RfdA.∫RfdA=
